About the Role

We are seeking a talented and passionate Backend Developer to significantly contribute to the product and business growth.

Who are you?

You have experience working in a product company (B2B SaaS experience is a plus) and have successfully deployed and maintained ReactJS frontends in production.

You have worked in teams of 3 to 5 members following Lean and Extreme Programming practices.

You have faced significant technical challenges and actively participated in product development.

You have ownership of making product and technical decisions, proactively identifying issues and opportunities.

Approximately 80% of services are in Node.js (plain JS and TypeScript), with 20% in Java Spring Boot.

Databases are PostgreSQL, and messaging uses RabbitMQ.

Frontends are built with ReactJS + Redux, employing a BFF pattern with GraphQL in Node.js.

Node.js microservices are distributed across various organizational domains, including pure microservices, API gateways, and GraphQL BFFs, written in plain JS or TypeScript.
